Twitter warned developers that private keys and tokens could have been exposed

In an email to developers, Twitter warned of a bug that may have exposed their private application keys and account tokens due to a mistake on how Twitter stored the information in the browser's cache.

"Prior to the fix, if you used a public or shared computer to view your developer app keys and tokens on developer.twitter.com, they may have been temporarily stored in the browser’s cache on that computer," the email read. "If someone who used the same computer after you in that temporary timeframe knew how to access a browser’s cache, and knew what to look for, it is possible they could have accessed the keys and tokens that you viewed."

Twitter shared that it has not yet seen any evidence that these keys were compromised, but alerted developers out of an abundance of caution.
